Salt build up can cause water blockages & engine overheating in all outboard motors. It can be worse if motor is left for longer periods without running, & especially if the motor isn't flushed for long enough (eg 510 minutes) to allow thermostat to open, & the cylinder / head to be flushed of salty water & filled with clean water while not in use) This is my challenge to see if i can get a motor running that has been classed as non viable to repair.
I also show how the water cooling system works throughout the cylinder & head & how outboards hold water while they aren't in use.

Happy boating!
